Severe burr flash on PPS products
Fenómeno do problema
PPS injection molded products have much flash and it is difficult to remove.
Análise das causas
PPS melt has low viscosity and extremely good fluidity, easily overflowing the parting line to produce flash; the flash is hard and brittle and difficult to remove.
Solução
Increase clamping force; fine parting line fitting; appropriately reduce injection pressure.
Conclusão principal
PPS low-viscosity flash is the norm and needs to be addressed through mold precision.
